Customers installing a recent version of the DLP Agent (12.5 and later) find that their Symantec Management Agent process (aka Altiris Agent, aexnsagent.exe) is restarted during the DLP Agent install.
This is true even if the customer never used Symantec Management Platform (aka Notification Server) in concert with Symantec DLP Agents.
Stop and start of the DLP Altiris Agent action is recorded in MSI log:

Symantec DLP used to have an Integration Component that allowed DLP Endpoint Agents to be managed by the Symantec Management Platform (v7.1 and earlier).
Thus, by default, DLP Endpoint Agent versions 12.0 and earlier registered on install with the Management Agent if present. In addition, the Management Agent is stopped and restarted by the DLP MSI process.
This is expected behavior, and as long as the process is successfully restarted, should not result in any problems with the Management Agent.
